Shaftless screw conveyor screw conveyor shaft compared with the traditions, the use of non-central axis design, the use of a certain flexibility in the overall steel auger material, which has the following outstanding advantages: strong anti-winding. No central axis interference, for conveyor-like, easy to wound materials have special advantages in using a non-central axis design, the use of a certain flexibility in the overall steel auger material, which has the following outstanding advantages: strong anti-winding. No central axis interference, for conveyor-like, easy to wound materials have special advantages shaftless screw conveyor uses: xLS series shaftless screw conveyor for conveying sewage treatment plant which gridlines fine grid spacing of 50mm decontamination screenings and filter press cake and other materials. Good environmental performance. Fully enclosed screw conveyor and easy to clean surface, to ensure the delivery of health and the environment from pollution materials, do not leak. Torque, low energy consumption. Because shaftless spiral, material clogging, discharge opening is not blocked, which can lower speeds, smooth transmission, reducing energy consumption. Torque up to 4000N / m. Transmission capacity. Transportation volume is 1.5 times the same diameter conventional shaft screw conveyor. Long distance transport. Single conveyor lengths up to 60 m. According to user needs, the use of multi-level series-mounted, ultra-long-distance transportation of materials. Can flex. Our development and production of mobile type shaftless screw conveyor, can maneuver work, a multi-purpose machine. Either beneath the material, but also ends the material. Using a special lining, the aircraft can operate at high temperatures. Compact, space-saving, good looks, easy to operate, economical and durable.
